so i think you might be okay with 3, but I don't know much about the PSu in ur sig but reading some reviews and such seems like it's pretty medicore PSU

I would go for a 1K watt/a 950w just to be safe if you're using 3 high end GPUs like anything higher than 4870s/5870s/6870s/GTX 580s. Depends what GPU you use, if you go tri 5770s then I would say maybe a 650w would do the job.

my corsair hx650 couldn't do it with any kind of oc on the gpu's or cpu. 850w ftw. each 5770=108w at stock volts and clocks. 750w will work.
